Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 5,041,213, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 5,041,213 | |
| -1 | -5,041,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,041,213.
Example:
1 x 5,041,213 = 5,041,213
and
-1 x -5,041,213 = 5,041,213
Notice both answers equal 5,041,213
With that explanation out of the way, let's continue. Next, we take the number 5,041,213 and divide it by 2:
5,041,213 ÷ 2 = 2,520,606.5
If the quotient is a whole number, then 2 and 2,520,606.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 5,041,213 | |
| -1 | -5,041,213 |
Now, we try dividing 5,041,213 by 3:
5,041,213 ÷ 3 = 1,680,404.3333
If the quotient is a whole number, then 3 and 1,680,404.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 5,041,213 | |
| -1 | -5,041,213 |
Let's try dividing by 4:
5,041,213 ÷ 4 = 1,260,303.25
If the quotient is a whole number, then 4 and 1,260,303.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 5,041,213 | |
| -1 | 5,041,213 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 71 | 101 | 703 | 1,349 | 1,919 | 2,627 | 3,737 | 7,171 | 49,913 | 71,003 | 136,249 | 265,327 | 5,041,213 |
| -1 | -19 | -37 | -71 | -101 | -703 | -1,349 | -1,919 | -2,627 | -3,737 | -7,171 | -49,913 | -71,003 | -136,249 | -265,327 | -5,041,213 |
